Abstract (en)
Provided is a three-dimensional deposition device (1) which forms a three-dimensional object by depositing a formed layer on a base unit (100), including: a powder supply unit which supplies a powder material; a light irradiation unit which irradiates the powder material with a light beam so that at least a part of the powder material irradiated with the light beam is sintered or melted and solidified to form a formed layer; a three-dimensional deposition chamber (2) which is sealed from an outside and accommodates the powder supply unit, the light irradiation unit, and a base unit (100); a gas discharge unit (37) which discharges a gas inside the three-dimensional deposition chamber (2); and a gas introduction unit (38) which introduces a predetermined gas into the three-dimensional deposition chamber (2). When the gas discharge unit (37) discharges a gas inside the three-dimensional deposition chamber (2) and the gas introduction unit (38) introduces a predetermined gas thereinto, a predetermined gas atmosphere is formed inside the three-dimensional deposition chamber (2).
